Solutions

Diagnóstico rápido

If the error occurs only when printing specific PDFs, the print language (PCL/PostScript) is at fault. If it appears during boot-up, the core firmware is likely corrupted.

Solución paso a paso

  1. Clear all print jobs from your PC queue.
  2. Run a firmware update via the official support website.
  3. Switch drivers (e.g., test a PCL driver instead of a PS one).
  4. Flush the print cache via the network configuration settings.

Prevención y mantenimiento

Perform firmware updates quarterly. Avoid sending massive, complex jobs without first ensuring your printer driver is current, as this reduces the likelihood of execution errors.

Cuándo llamar a un técnico

If the error 900 remains post-update, the main controller board may have sustained permanent flash memory corruption.
